综合评价法确定岩质顺向坡软弱结构面的强度参数OA
Determination of Strength Parameter of Weak Structural Plane of Consequent Rock Slope by Comprehensive Eval-uation Method
岩质边坡的勘察相对较为简单，不像土质边坡那样当岩土结构复杂时使得勘察较为困难，但当岩质边坡为顺向坡、且有软弱夹层时，其软弱结构面抗剪强度指标的确定一直是勘察人员难以把握的问题。结合工程实例，通过结构面大型现场直剪试验、规范查表法及反算法等综合评价法，确定了岩质边坡软弱结构面的抗剪强度指标，并对各方法进行了详细的介绍和分析，以供类似工程作对比参考
The investigation of rock slope is easier than that of soil, because geotechnical structure is not that complex.But for the consequent rock slope with weak interlayer, the determination of shear strength indexes of weak structural plane has been difficult to grasp.Combined with the engineering case, according to the comprehensive evaluation by direct shear test, standard lookup method and inverse algorithm, shear strength indexes of weak structure of rock …查看全部>>
